In the movie
Holes the animals shown in the movie and referred to as yellow spotted lizards are in fact Bearded Dragons with good
makeup and CGI fangs. The Bearded Dragons were provided by the Sandfire Dragon Ranch.

Since
the 1960s, Australia has strictly
prohibited exports of any native wildlife. It is believed that the "founder stock" of captive bred Bearded Dragons found outside
of Australia today were smuggled out of the country between 1974 and 1990.
